Performance Large Series Vertical Machining Center OVERVIEW VMC Large Series have versatility and capacity to carryout maximum range of jobs, specially bigger size heavy components like Die & Mould within the working envelop with total mechanical & thermal stability of structural parts. Special unique structure of broad base made out of graded casting dampens the effect of vibration delivering capability of high dynamics, better accuracy with precision and higher material removal rate. Such a complete package design machine thus enables better stability for large size work pieces such as injection moulds, forging dies, large plates enabling manufacturers to keep pace with growing and demanding market applications.
j y o t i. c o. i n WIDER MACHINE BASE Unique T-Base construction design to deliver optimum surface quality during demanding cutting conditions and avoid overhanging problem for heavy workpiece load on table. Overhanging Throughout Base Support T- Base Design Conventional Design TRIANGULAR SADDLE Rigid triangular shape saddle provides excellent strength and stability during high cutting condition even for heavy weight components. STEP-UP BED CONSTRUCTION Step-up bed structure concept with widely spread guideways provides structural stability during demanding dynamic cutting condition for entire Y-Axis movement. Add on to this such design creates condition of one side flow directly into chip conveyor enhancing efficient chip disposal MULTIPLE BASE SUPPORT Broader footprint covering entire structural moving parts ensures excellent stability and vibration free cutting during heavy cutting load conditions.
Performance Large Series Vertical Machining Center BROADER COLUMN Broad column construction upto 50% height of the column help for better stability & balancing during extreme conditions at Z-Axis. Headstock length almost equal to its width which reduces cantilever effect. 50% 75% 50% 25% PRECISION LINEAR AXIS X-Axis saddle moving on bed (Roller Type LM Guideways with 8-LM blocks). Y-Axis supporting broad table movement on saddle (3- Roller Type LM Guideways with 6-LM blocks). This drastically increases stability in full working area during dynamic as well as static load conditions with higher machining rates while enhancing geometrical accuracy and surface quality of the machined workpieces. Also this design avoids buckling effect for bigger table with heavy load. 3 LM Support Buckling Effect * Structure of VMC 1870 / 1880
j y o t i. c o. i n DIRECT COUPLED BALL SCREW Recirculating precision class ball screw directly coupled with axis motor for long term accuracy EFFICIENT CHIP FLOW One side slope helps for efficient chip flow. With such design chips will directly fall down into conveyor with help of flush coolant and spindle around coolant system. WIDE WORKING AREA

Operator platform for easy reach at machining area. Machine Tower light & Tool Display Unit for total conformity. o 90 o 0 IMPROVED MAINTENANCE TPM friendly units which required regular checking like pneumatics, electrical panel, lubrication are conveniently located for easy maintenance at the rear of the machine well within the reach of operator. Ladder for easy reach to ATC for loading/unloading & Maintenance purpose
j y o t i. c o. i n HIGH PERFORMANCE SPINDLE All spindles are designed and manufactured in-house to achieve high reliability and consistency for better working life. Specially designed spindle with ceramic bearing also available to choose from, for continuous machining at higher rpm, especially for Die & Mould applications. FAST AUTO TOOL CHANGER The auto tool changer is a Twin Arm Type with Disc type tool magazine capable of storing tools at a time. The tool change time is 2.4 seconds. An option of 24, 40 tool magazines are also available. PRODUCTIVITY IMPROVEMENT OPTIONS HIGH SPEED ELECTRO SPINDLE High Speed High Torque Motorized Spindles with 100/15000/18000 rpm are available which are manufactured in-house for high speed machining. The peak speed for such spindles reaches in 2.5 secs while deceleration time is only 2 secs.
Performance Large Series Vertical Machining Center PRODUCTIVITY IMPROVING OPTIONS th th 4 AND 5 AXIS CAPABILITY For maximum application & contouring flexibility, 4th & 5th axis table with high resolution feedback system can be used to avoid multiple set-up & do multiple side machining in single set-up to reduce the over-all cycle time. TOOL PROBE AND JOB PROBE A wide choice of spindle and surface-sensing probes as tool and job probes with infrared/radio/laser transmission technology are available for increased spindle utilization and reduce non productive time COOLANT THROUGH SPINDLE CTS provides high pressure filtered coolant directly to the cutting edge minimizing heat distortion, ensuring maximum productivity with today s high performance tooling. Highly recoend for jobs demanding deep hole drilling and tapping. GEAR BOX Gear Box option with auto shifting mechanism available for special applications requiring high cutting torque at lower rpm for harder material.
